## Questions & Answers

**Q: Does this work for urethane paint?**
A: Yea

**Q: I should spray this product and then primer ?**
A: You wouldn’t need primer if you’re already using this for painting plastic, just spray the adhesion promoter first then your choice of paint

**Q: Painting fender flairs rough plastic on my truck Will this smooth the plastic texture to spray a base coat to match the rest of the car**
A: No, I used it for the same purpose on my jeep. It only puts a light coating that is sticky to the primer. I would light sand (rough the surface) of the fender, clean, use the adhesion promoter and then a primer coat before painting.

**Q: Can I use this on glass?**
A: No
